North Korea displays apparently new missiles as U.S. carrier group approaches| Reuters

North Korea displayed what appeared to be new long-range and submarine-based missiles on the 105th birth anniversary of its founding father, Kim Il Sung, on Saturday, as a nuclear-powered U.S. aircraft carrier group steamed toward the region.

Missiles appeared to be the main theme of the giant parade, with Kim's grandson, leader Kim Jong Un, taking time to greet the commander of the Strategic Forces, the branch of the military that oversees the missile arsenal.

A U.S. Navy attack on a Syrian airfield this month with Tomahawk missiles raised questions about U.S. President Donald Trump's plans for reclusive North Korea, which has conducted several missile and nuclear tests in defiance of U.N. sanctions, regularly threatening to destroy the United States.

Kim Jong Un, looking relaxed in a dark suit and laughing with aides, oversaw the festivities on the "Day of the Sun" at Pyongyang's main Kim Il Sung Square.

Goose-stepping soldiers and marching bands filled the square, next to the Taedonggang River that flows through Pyongyang, in the hazy spring sunshine, followed by tanks, multiple-launch rocket systems and other weapons.
